3 Claims.

This invention relates to improvements infolding camp stoves and has special reference to improved leg structures for such stoves.

' The camp stoves to which my invention relates are the type which close up into suit-case form for transportation from place to place. One broad side'of the case constitutes a cover which is hinged to thecase to be opened up when the stove is to be used and my improvementcom- 1'0 prises U-shaped bail-like legs, one at each end of the case, and arranged to be swung to a closed position to hold the case closed for transportation and to be swung to a case opened position for supporting the case for use with its lower side or bottom free of the surface upon. which the case is placed for using the stove;-

- The invention resides in improved and simplified means for retaining the legs both in case opened and in case closed positions,

The invention will be more readily understood from the following description taken in conjunction with the accompanying drawing, form ing part of this specification, and also in view of the appended claims.

In said drawing:-

Fig. 1 is a top plan view of the stove shown in closed condition;

Fig. 2 is an enlarged end view of same;

Fig. 3 is an enlarged vertical section on the line 33 of Fig. l and showing one of the leg members in case closed position in full lines and open in dotted lines;

Fig. 4 is a fragmentary vertical section on the line 4-4 of Fig. 3 particularly showing the leg member in case closed position; and

Fig. 5 is a section similar to Fig. 4, but showing the leg member in case open position.

The case Ill of the stove is made of a shallow open topped rectangular box II and is adapted 4.0 to be closed, when'not in use, by a fiatcover l2 hinged, as shown at I3, to the back wall [4 of the case.

At each end of the case there is arranged a bail-like U-shaped leg member l5 each made of 45 a fiat bar bent to provide a middle portion l6, adapted to span the end portion of the cover l2, and parallel leg parts I! which are arranged to lie flat against the back wall 14 and the front wall l8 respectively of the case. The free ends 50 of the leg parts ll of the leg members iii are pivotally secured to the front and back walls [8 I and M as shown at 19. Each leg member I5 is adapted to be swung up on its pivots H) to case closed position, as shown in Figs. 3 and 4, when 55 the middle part [6 of the leg member lies close to and in substantial contact with the cover l2 thus preventing the cover from opening and maintaining the case closed, and also to be swung down to a; position where it depends from its pivots below the case, as shown in dottedlines: '5' in Fig. 3 and in full lines in Fig. 5. In this latter position of the leg members the cover l2 can be freely opened.

llhe pivots ISare so arranged relatively to the height of the case that: when the leg members are 10 swung down to case open position the middle portions N3 of the leg members are spacedbelow the bottom 28 of the case as best shown inFig. 5. Consequently these" leg :members serve to hold the case spaced above the support upon which 15 the stove is placed for use for permitting air to freely enter the case through inlet openings 2| in the bottom 26 for combustion purposes.

For the purpose of positioning the leg members in case open position that is depending from the 20 pivots 19 there is provided a projection 22 extending inwardly preferably from one edge of the middle part l6 of each leg l5, which is long enough to swing into contact with the bottom 2!! of the case when the leg member l5 extends 25 straight down from its pivots l9.

When the projection 22 contacts with'the bottom 20 it retains the leg member against swinging inwardly any further, in an obvious manner.

While the pivotal connections of the leg mem- 3Q bers I5 with the case could be made just tight enough to assure theretention of the leg members against being inadvertently moved from their case open positions I prefer to provide simple means for interlocking these members with 35 the case in such a manner that by the use of relatively slight force the leg members can be locked in open position or as readily unlocked.

In the form of the invention shown in the drawing this interlock consists of depressions 40 23 formed upwardly in the bottom 2!] of the case one near each end and of a shape and in a position to receive the freeends of the projections 22.

The construction is such that in swinging the leg member l5 around beneath the case the projection 22 snaps into the depression 23 and is definitely held in such position by the resiliency of the parts until the leg member is intentionally pulled outwardly with sufficient force to cause the projection to spring out of the depression and after such release the leg member can be easily swung upward to lock the case closed, as best shown in Fig. 3.

It is obvious that the side wall of the depression over which the free end of said projection .35 leg member, pivotally mounted to swing over the 22 snaps, as it is swung to case supporting position is the part which functions to retain the leg in such position and constitutes a leg retaining shoulder.

Preferably as explained the projection 22 extends from one edge of the middle portion iii of the leg member l5 and the edge from which it extends is the outer edge 24 when the leg member is in case closed position in which position the projection 22 is adapted to contact with the adjacent end wall 22' of the case. Also preferably as shown the projection 22 constitutes one leg of an L-shaped member 25 the other leg 26 being secured to the inner surface of the middle leg part l6 of the leg member l5 and in position to contact with the cover l2 of the case. The arrangement is such that the parts 26 have to be sprung over the adjacent end of the cover with sufiicient force so that the resiliency of the parts will retain the leg members in case closed position until they are intentionally pulled off the ends of the case preparatory to opening the case for use.

It should be understood that suitable burners and other appliances, not shown, are housed within the case.

As many modifications of the invention will readily suggest themselves to oneskiiled in the art I do not limit or confine the invention to the specific details of construction herein shown and described except within the scope of the appended claims.

I claim:

1. In a folding camp stove a U-shaped bail-like end of the case to a position where the connecting bar of the leg lies above the cover of the case and also to a position where said bar is positioned below the bottom of the case for supporting same,

a projection extending inwardly from the connecting bar of the leg, the arrangement being such that when the bail is swung to case closed position said projection will contact the end wall of the case, and when swung to case opened position the projection will contact the bottom of the case and a shoulder on the lower surface of the bottom of the case over which the free end of said projection springs when the bail is swung down to case supporting position.

2. In a folding camp stove a U-shaped bail-like leg member, pivotally mounted to swing over the end of the case to a position where the connecting bar of the leg lies above the cover of the case and also to a position where said bar is positioned below the bottom of the case for supporting same, a projection extending inwardly from the connecting bar of the leg, the arrangement being such that when the bail is swung to case closed position said projection will contact the end wall of the case, and when swung to case opened position the projection will contact the bottom of the case, and the bottom of the case provided with a small depression into which the free end of said projection snaps when the leg is swung down to case supporting position.

3. In a folding camp stove a leg pivotally mounted on the case and having a part adapted to be swung above the cover of the case when the case is closed and also to be swung to a position I below the bottom of the case for supporting same, said part having a projection arranged and adapted to contact the bottom of the case when the leg is swung to supporting position, and the bottom of the case having a shoulder arranged and adapted to cooperate with said projection for yieldingly retaining the leg in supporting position.
